Federal freecoaster hub V4 now with hubguards. This hub uses the same technology as the previous versions with the spacers for an adjustable gap with updated reliable hardware. Comes in 9t only. When ordering let us know in the special instructions whether you would like the gap setup either x-large, large, medium or small & we can adjust this for you.
